• Description:
  In response to a request from management, an investigation was begun into worker exposures at the Toledo Street Facility of General Castings (SIC-3321), Delaware, Ohio. The facility was a gray and ductile iron foundry with 55 workers on three shifts. Personal breathing zone concentrations of respirable silica (14808607) ranged from 31 to 284 micrograms per cubic meter (microg/m3) as time weighted averages (TWAs). Of the 16 nearly full shift samples taken, six exceeded the OSHA Permissible Exposure Limit of 100microg/m3. Benzene (71432S) was detected in one sample for a molder at 0.1 parts per million (ppm), equal to the NIOSH recommended limits. Formaldehyde (50000) concentrations in the area ranged from 0.012 to 0.026ppm. Carbon-monoxide (630080) concentrations ranged from 2 to 30ppm with five of the ten personal breathing zone samples exceeding the accepted levels. Phenol (108952) at 0.07 to 0.54ppm, isopropanol (67630) at 1 to 38ppm, toluene (108883) at less than 0.062 to 0.066ppm, and the metals aluminum (7429905), chromium (7440473), copper (7440508), iron (7439896), magnesium (7439954), manganese (7439965), lead (7439921), and zinc (7440666), did not exceed the recommended limits. The authors conclude that there was a hazard from respirable silica, carbon-monoxide, formaldehyde, and benzene exposures in the coremaking, molding, and shakeout areas. The authors recommend that engineering controls, an improved respiratory protection program, and improved work practices be implemented to reduce exposures.
